Description

Technical Field

[0001] This invention relates to the field of coal conveying equipment technology, specifically to an automatic feeding device that prevents coal raw materials from being crushed. Background Technology

[0002] In the process of conveying and feeding coal raw materials, related screw conveyor equipment is usually used. When in use, the rotation of the screw blades installed inside the machine body will transport the coal raw materials fed into the hopper from one end to the other along the internal channel of the machine body.

[0003] However, the existing screw conveyor equipment generally has a simple and straightforward feeding structure. It typically uses a direct feeding method for coal lumps, resulting in continuous feeding without control over the quantity. When too many coal lumps are fed at once or continuously, the limited processing capacity of the screw conveyor prevents it from transporting a large amount of coal into the equipment in time. This leads to coal accumulation at the feed hopper, causing blockages. These blocked coal lumps are subjected to intense compression and friction under the rotation of the screw conveyor blades and gravity, increasing the breakage rate. This not only prevents the screw conveyor from functioning properly, affecting subsequent coal processing, but also exacerbates wear and tear, shortens the equipment's lifespan, and increases maintenance costs due to prolonged blockages and overload operation.

[0004] Therefore, in view of this, the present invention proposes an automatic feeding device to prevent coal raw materials from being crushed and broken, in order to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an automatic feeding device to prevent coal raw materials from being crushed and broken, thereby resolving the corresponding technical issues raised in the background section.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automatic feeding device for preventing the crushing of coal raw materials, comprising a machine body, wherein a feed hopper is fixedly connected to the upper outer surface of the front side of the machine body, and a discharge hopper is fixedly connected to the lower outer surface of the rear side of the machine body, wherein the feed hopper and the discharge hopper are arranged far apart, and a fixed frame is fixedly connected to one end of the machine body facing the feed hopper, wherein the fixed frame is arranged outside the feed hopper, and further comprising: an intermittent feeding mechanism, a follow-up tapping mechanism, and a water mist spraying mechanism, wherein the intermittent feeding mechanism, the follow-up tapping mechanism, and the water mist spraying mechanism are all arranged between the fixed frame and the feed hopper;

[0007] The intermittent feeding mechanism is used to intermittently feed coal raw materials;

[0008] The follow-up tapping mechanism is used to tap the outer wall of the feed hopper simultaneously while the coal raw material is intermittently fed.

[0009] The water mist spraying mechanism is used to spray water mist into the interior of the machine body simultaneously while the coal raw material is intermittently fed.

[0010] Preferably, the intermittent feeding mechanism includes a drive motor fixedly connected to the fixed frame, the output end of the drive motor being fixedly connected to a rotating shaft, and the rotating shaft being rotatably connected between the inner walls on both sides of the fixed frame.

[0011] Preferably, a central shaft is rotatably connected between the inner walls of both sides of the fixed frame, and the central shaft is rotatably connected through the feed hopper. A material plate is fixedly connected in an annular shape at equal intervals on the outer surface of the middle part of the central shaft, and the material plate is set inside the feed hopper. A pendulum wheel is symmetrically fixedly connected to the outer surface of both ends of the central shaft, and a turntable is symmetrically fixedly connected to the outer surface of both ends of the rotating shaft. A lever is fixedly connected to one side of each turntable off-center, and the lever is used to rotate the pendulum wheel.

[0012] Preferably, the follow-up tapping mechanism includes a linkage shaft symmetrically rotatably connected to the inner walls of both sides of the fixed frame, and a transmission component is connected between the linkage shaft and the rotating shaft, and a cam is fixedly connected to the outer surface of the linkage shaft.

[0013] Preferably, the follow-up tapping mechanism further includes an arc-shaped tapping plate symmetrically fitted to the outside of the feed hopper, and a first spring is fixedly connected between the arc-shaped tapping plate and the fixed frame. An extension rod is symmetrically fixedly connected to each side of the arc-shaped tapping plate away from the other side. A fixed block is fixedly connected to each end of the extension rod away from the other side. A pressure ball is fixedly connected to the side of the fixed block facing the cam. The cam is used to squeeze and push the pressure ball to move.

[0014] Preferably, U-shaped frames are symmetrically fixedly connected to the inner walls on both sides of the fixed frame, and a linkage frame is rotatably connected between the opposite sides of the U-shaped frames, with straight slots symmetrically opened at both ends of the linkage frame.

[0015] Preferably, each of the arc-shaped striking plates on the opposite side of the arc surface is fixedly connected to an I-shaped rod, and the I-shaped rod is slidably connected to the fixing frame. Each of the I-shaped rods on the same side is fixedly connected to a sliding column at one end facing each other, and the sliding column is slidably connected to the straight groove.

[0016] Preferably, the water mist spraying mechanism includes a water storage ring fixedly connected to the bottom of the fixed frame, a water guide pipe fixedly connected to the water storage ring, an annular top plate slidably connected to the outer ring surface of the feed hopper, vertical rods fixedly connected at equal intervals in an annular shape at the bottom of the annular top plate, and a piston rod fixedly connected to the bottom of the vertical rods.

[0017] Preferably, a T-shaped water supply pipe is fixedly connected to the water storage ring at equal intervals. The end of the T-shaped water supply pipe away from the water storage ring passes through the feed hopper, and an atomizing nozzle is fixedly connected to the end of the T-shaped water supply pipe that passes through the feed hopper. The piston rod is slidably connected to the T-shaped water supply pipe in a sealed manner. A second spring is fixedly connected between the T-shaped water supply pipe and the vertical rod, and the second spring is sleeved on the outside of the piston rod.

[0018] Preferably, the water mist spraying mechanism further includes a sector gear fixedly connected to the opposite side of the linkage shaft, and a toothed plate fixedly connected to the vertical rod near the sector gear, and the toothed plate meshing with the sector gear.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) When the coal raw material is fed into the machine body through the feed hopper, the rotation of the rotating shaft is controlled by the drive motor, so that the disc and the lever installed on it can rotate synchronously. By using the lever to push the flower wheel, the material plate can be driven to rotate intermittently inside the feed hopper. Due to the special shape design of the flower wheel, and the fact that the rotation angle of the flower wheel is equal each time the lever pushes it, and the moving speed of the lever when it follows the rotation of the rotating shaft is consistent, the time for the flower wheel to be pushed each time is also equal. Thus, the receiving time of each two adjacent material plates is consistent, and the amount of coal raw material received is also the same. During the subsequent rotation and unloading, the coal raw material enters the machine body in an intermittent manner for conveying, effectively preventing the coal from accumulating and blocking in the feed hopper. This design ensures the continuity and stability of the conveying process. Simultaneously, the intermittent rotation of the material plates feeds a fixed amount of coal into the machine each time, avoiding blockages caused by a large influx of coal. This provides time for the coal in the hopper to rearrange and disperse, further reducing the risk of blockage. Because the material plates are equidistant, the amount of coal entering the machine each time remains consistent, preventing excessive coal feeding that could cause blockages at the connection between the hopper and the machine. This effectively reduces coal accumulation and prevents coal from being crushed, which could lead to a large amount of coal residue remaining inside the machine, affecting coal transportation and the normal operation of the machine.

[0021] (2) During the process of intermittently feeding coal blocks by rotating the lever to drive the plum blossom wheel, the transmission connection of the transmission component can drive the linkage shaft to rotate synchronously with the cam installed on it when the shaft rotates, and intermittently squeeze the pressure ball set on the side of the cam. With the design of the first spring, the arc-shaped patting plate can move back and forth on the side of the feed hopper, forming a patting effect on the outer wall of the feed hopper. The outer wall of the feed hopper vibrates during the patting process. This vibration can effectively shake off the coal dust and impurities attached to the inner wall of the feed hopper, keep the feed hopper clean, reduce the interference of impurities on the coal block transportation, promote the smooth feeding of coal blocks, avoid the problem of blockage or uneven feeding caused by coal dust and impurities, and thus improve the coal block transportation efficiency.

[0022] The cam consists of a circular ring structure and a protruding part, while the pressure ball is a spherical object. Both the cam and the pressure ball have smooth outer surfaces. When the protruding part of the cam contacts the pressure ball, because the diameter of the protruding part of the cam is larger than the diameter of the circular ring structure, the rotation of the cam can create a squeezing effect on the pressure ball, pushing it away from the cam. With the design of the first spring, as the cam continues to rotate, the arc-shaped striking plate can strike the outer wall of the feed hopper. The side of the cam is designed to cooperate with the pressure ball. Through the intermittent squeezing of the pressure ball by the rotation of the cam, the arc-shaped striking plate can move back and forth regularly, producing an effective and stable striking effect. This ensures that the force and time of each strike on the outer wall of the feed hopper by the arc-shaped striking plate are consistent. The design of the first spring can play a reset role in this process. When the cam stops squeezing the pressure ball, the first spring can push the arc-shaped striking plate to reset, preparing for the next striking action.

[0023] (3) During the process of patting the outer wall of the feed hopper, the rotation of the linkage shaft can not only drive the cam to rotate, but also drive the sector gear to rotate synchronously, mesh the tooth plate and drive it to move vertically. With the help of the second spring set between the vertical rod and the T-shaped water pipe, the sector gear can drive the piston rod to move up and down inside the T-shaped water pipe while rotating continuously, and draw water from the water storage ring, so that the water source is sprayed out from the atomizing nozzle in the form of atomized water mist. Since the atomizing nozzle is set in the feed hopper, the water mist sprayed by the atomizing nozzle will directly act on the surface of the coal raw material, spraying water mist on the coal raw material during the feeding process, so as to avoid the coal raw material from becoming too dry in the dry environment, which would cause the feeding to be squeezed and broken.

[0024] The T-shaped water pipes are arranged in a ring at equal intervals on the water storage ring, which allows multiple atomizing nozzles to be evenly distributed in different positions within the feed hopper. During use, the coal raw material can be sprayed from different directions, thereby increasing the uniformity of water mist reception on the coal and further improving the effect of spraying water mist onto the coal raw material. This helps to increase the moisture content of the coal raw material and prevent it from becoming too dry. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Embodiments of the present invention:

[0041] Please refer to Figures 1 to 9 As shown, an automatic feeding device for preventing coal raw materials from being crushed by compression includes a body 1. A feed hopper 2 is fixedly connected to the upper outer surface of the front side of the body 1, and a discharge hopper 3 is fixedly connected to the lower outer surface of the rear side of the body 1. The feed hopper 2 and the discharge hopper 3 are arranged far apart. A fixed frame 4 is fixedly connected to one end of the body 1 facing the feed hopper 2, and the fixed frame 4 is arranged outside the feed hopper 2. The device also includes an intermittent feeding mechanism 5, a follow-up tapping mechanism 6, and a water mist spraying mechanism 7. The intermittent feeding mechanism 5, the follow-up tapping mechanism 6, and the water mist spraying mechanism 7 are all arranged between the fixed frame 4 and the feed hopper 2.

[0042] The intermittent feeding mechanism 5 is used to intermittently feed coal raw materials.

[0043] The follow-up tapping mechanism 6 is used to tap the outer wall of the feed hopper 2 simultaneously while the coal raw material is intermittently fed.

[0044] The water mist spraying mechanism 7 is used to spray water mist into the interior of the machine body 1 simultaneously while the coal raw material is intermittently fed.

[0045] The intermittent feeding mechanism 5 includes a drive motor 501 fixedly connected to the fixed frame 4. The output end of the drive motor 501 is fixedly connected to a rotating shaft 502, and the rotating shaft 502 is rotatably connected between the inner walls on both sides of the fixed frame 4.

[0046] A central shaft 505 is rotatably connected between the inner walls of both sides of the fixed frame 4, and the central shaft 505 is rotatably connected through the feed hopper 2. A material plate 507 is fixedly connected in an annular shape at equal intervals on the outer surface of the middle part of the central shaft 505, and the material plate 507 is set inside the feed hopper 2. A plum blossom wheel 506 is symmetrically fixedly connected to the outer surface of both ends of the central shaft 505. A turntable 503 is symmetrically fixedly connected to the outer surface of both ends of the rotating shaft 502. A lever 504 is fixedly connected to one side of the turntable 503 off-center, and the lever 504 is used to rotate the plum blossom wheel 506.

[0047] The effect achieved by this embodiment is as follows: when the coal raw material is fed into the machine body 1 through the feed hopper 2, the receiving time of each two adjacent material plates 507 is consistent, and the amount of coal raw material received is also the same. During the subsequent rotating and unloading process, the coal raw material enters the machine body 1 intermittently for conveying, effectively preventing the coal from accumulating and blocking in the feed hopper 2, and ensuring the continuity and stability of the conveying process.

[0048] Furthermore, since the material plates 507 are equidistantly spaced, the amount of coal raw material entering the machine body 1 each time is kept consistent. This prevents excessive coal raw material from being fed into the machine body 1, which could cause blockage at the connection between the feed hopper 2 and the machine body 1. It effectively reduces the accumulation of coal raw material and avoids the coal raw material from being squeezed and broken, which would result in a large amount of coal residue remaining inside the machine body 1, affecting the transportation of coal raw material and the normal use of the machine body 1.

[0049] Further examples:

[0050] Please refer to Figures 1 to 9 As shown, the follow-up tapping mechanism 6 includes a linkage shaft 602 symmetrically rotatably connected to the inner walls on both sides of the fixed frame 4, and a transmission component 601 is connected between the linkage shaft 602 and the rotating shaft 502. A cam 603 is fixedly connected to the outer surface of the linkage shaft 602.

[0051] The follow-up tapping mechanism 6 also includes an arc-shaped tapping plate 607 symmetrically fitted to the outside of the feed hopper 2, and a first spring 608 is fixedly connected between the arc-shaped tapping plate 607 and the fixed frame 4. An extension rod 606 is symmetrically fixedly connected to the arc surface of the arc-shaped tapping plate 607 on the side away from each other. A fixed block 604 is fixedly connected to the end of the extension rod 606 on the side away from each other. A pressure ball 605 is fixedly connected to the side of the fixed block 604 facing the cam 603. The cam 603 is used to squeeze and push the pressure ball 605 to move.

[0052] U-shaped frames 613 are symmetrically fixedly connected to the inner walls on both sides of the fixed frame 4. A linkage frame 611 is rotatably connected between the opposite sides of the U-shaped frames 613. Straight slots 612 are symmetrically opened at both ends of the linkage frame 611.

[0053] Each of the arc surfaces of the arc-shaped striking plate 607 away from the arc surface is fixedly connected with an I-shaped rod 609, and the I-shaped rod 609 is slidably connected to the fixed frame 4. Each of the I-shaped rods 609 on the same side is fixedly connected to a sliding column 610 at one end facing each other, and the sliding column 610 is slidably connected to the straight groove 612.

[0054] The effects achieved by this embodiment are as follows: During the process of the intermittent rotation of the paddle wheel 504 driving the intermittent rotation of the plum blossom wheel 506 and the intermittent quantitative feeding of coal raw materials using the material plate 507, the arc-shaped tapping plate 607 can tap the outer wall of the feed hopper 2, causing the outer wall of the feed hopper 2 to vibrate during the tapping process. This vibration can effectively shake off the coal dust and impurities attached to the inner wall of the feed hopper 2, keeping the feed hopper 2 clean, reducing the interference of impurities on the coal conveying, promoting the smooth feeding of coal, avoiding the problems of blockage or uneven feeding caused by coal dust and impurities, thereby improving the coal conveying efficiency.

[0055] A further embodiment:

[0056] Please refer to Figures 1 to 9 As shown, the water mist spraying mechanism 7 includes a water storage ring 702 fixedly connected to the bottom of the fixed frame 4, a water guide pipe 703 fixedly connected to the water storage ring 702, an annular top plate 710 slidably connected to the outer ring surface of the feed hopper 2, vertical rods 708 fixedly connected at equal intervals in an annular shape at the bottom of the annular top plate 710, and a piston rod 706 fixedly connected to the bottom of the vertical rods 708.

[0057] A T-shaped water supply pipe 704 is fixedly connected to the water storage ring 702 at equal intervals in a ring shape, and a one-way valve is provided between the T-shaped water supply pipe 704 and the water storage ring 702. The end of the T-shaped water supply pipe 704 away from the water storage ring 702 passes through the feed hopper 2, and the end of the T-shaped water supply pipe 704 passing through the feed hopper 2 is fixedly connected to an atomizing nozzle 705. The piston rod 706 is sealed and slidably connected to the T-shaped water supply pipe 704. A second spring 707 is fixedly connected between the T-shaped water supply pipe 704 and the vertical rod 708, and the second spring 707 is sleeved on the outside of the piston rod 706.

[0058] The water mist spraying mechanism 7 also includes a sector gear 701 fixedly connected to the opposite side of the linkage shaft 602, and a toothed plate 709 fixedly connected to the vertical rod 708 near the sector gear 701, and the toothed plate 709 meshes with the sector gear 701.

[0059] The effect achieved by this embodiment is as follows: During the process of patting the outer wall of the feed hopper 2, the piston rod 706 can be driven to move up and down reciprocally inside the T-shaped water pipe 704, drawing water from the water storage ring 702, so that the water is sprayed out from the atomizing nozzle 705 in the form of atomized water mist. Since the atomizing nozzle 705 is set inside the feed hopper 2, the water mist sprayed by the atomizing nozzle 705 will directly act on the surface of the coal raw material being fed, spraying water mist on the coal raw material during the feeding process, avoiding the coal raw material from becoming too dry in a dry environment, which would cause the material to be squeezed and broken during feeding.

[0060] The complete usage steps and working principle of the above embodiments are as follows:

[0061] The following describes the intermittent feeding process of the intermittent feeding mechanism 5 for coal lumps:

[0062] During use, coal raw material enters the machine body 1 through the feed hopper 2. The interior of the machine body 1 is as follows: Figure 2 The device shown is equipped with spiral blades. The rotation of these blades conveys the coal raw material, which is then discharged from the discharge hopper 3. Simultaneously, as the coal raw material enters the feed hopper 2, ... Figure 2 and Figure 5As shown, a rotating shaft 502 and a central shaft 505 are rotatably connected between the inner walls of both sides of the fixed frame 4. The rotating shaft 502 is fixedly connected to the output end of the drive motor 501. The central shaft 505 is rotatably connected to the feed hopper 2. A material plate 507 is fixedly arranged in an annular shape at equal intervals on the outer surface of the central shaft 505, ensuring that the distance between adjacent material plates 507 is equal. When coal raw material is fed into the feed hopper 2, it will preferentially fall into the gap formed between adjacent material plates 507. At the same time, the drive motor 501 synchronously drives the rotating shaft 502 to rotate. Turntables 503 are symmetrically fixed to the outer surfaces of both ends of the rotating shaft 502. A lever 504 is fixedly mounted on the opposite side of the turntables 503. A swivel wheel 506 is symmetrically fixed to the outer surfaces of both ends of the central shaft 505, and the swivel wheel 506 and the lever 504 are compatible. When the drive motor 501 drives the rotating shaft 502 to rotate on the fixed frame 4, the turntables 503 will rotate synchronously with the rotation of the rotating shaft 502. At this time, the position of the lever 504 changes synchronously. The lever 504 can drive the swivel wheel 506 to rotate intermittently. The material plate 507 rotates synchronously around the central shaft 505 via its connection to the central shaft 505. Coal lumps falling between adjacent material plates 507 are then conveyed from the feed hopper 2 into the machine body 1 under the rotation of the material plate 507. During this process, the intermittent feeding mechanism 5 ensures that the rotation angle of the flower wheel 506 is equal each time the lever 504 is turned, and the moving speed of the lever 504 is consistent. This ensures that the time for the flower wheel 506 to be turned is also equal each time, thus making the receiving time of each pair of adjacent material plates 507 consistent. The quantity of coal raw materials is also the same. During subsequent rotating and unloading, the coal raw materials enter the machine body 1 intermittently for conveying. Since the material plates 507 are equidistant, the quantity of coal raw materials entering the machine body 1 each time is kept consistent. This prevents excessive coal raw material from being fed into the machine body 1, which could cause blockage at the connection between the feed hopper 2 and the machine body 1. It also reduces the accumulation of coal raw materials and avoids the coal raw materials from being squeezed and broken, which could result in a large amount of coal residue remaining inside the machine body 1, affecting the transportation of coal raw materials and the normal use of the machine body 1.

[0063] Please refer to the above work process. Figures 1 to 9 .

[0064] The following describes the working process of the follow-up beating mechanism 6 simultaneously beating the outer wall of the feed hopper 2 while the coal raw material is intermittently fed:

[0065] While the drive motor 501 drives the rotating shaft 502 to rotate on the fixed frame 4, as Figure 2 , Figure 4 , Figure 5 as well as Figure 6As shown, the lower end of the rotating shaft 502 is connected to the linkage shaft 602 via the transmission component 601, and the linkage shaft 602 is rotatably connected to the fixed frame 4. A cam 603 is fixedly installed on the outer surface of the linkage shaft 602. Initially fitted arc-shaped striking plates 607 are symmetrically arranged on the outer side of the feed hopper 2, and a fixed block 604 is fixedly connected to the arc-shaped striking plate 607 via two symmetrical extension rods 606. A pressure ball 605 is installed on the fixed block 604 facing the cam 603. When the rotating shaft 502 rotates, the transmission component 601 drives the linkage shaft 602 to rotate synchronously with the fixed frame 4. (It should be noted that the transmission component 601 consists of two transmission wheels and a transmission belt connecting the two transmission wheels. The two transmission wheels are respectively fixedly connected to the outer surfaces of the rotating shaft 502 and the linkage shaft 602. When the rotating shaft 502 rotates, the transmission belt drives the two...) The transmission wheels rotate synchronously, so that when the rotating shaft 502 rotates, the linkage shaft 602 can rotate synchronously on the fixed frame 4. When the linkage shaft 602 rotates, the cam 603 installed on the linkage shaft 602 rotates synchronously and moves closer to the pressure ball 605. When the cam 603 contacts the pressure ball 605, since the first spring 608 is fixedly connected between the arc-shaped striking plate 607 and the fixed frame 4, initially, under the elastic force of the first spring 608, the arc-shaped striking plate 607 can be driven to approach the outer wall of the feed hopper 2. By setting the connection method of the first spring 608, the arc-shaped striking plate 607 can be movable and its position can be changed. When the cam 603 contacts the pressure ball 605, the pressure ball 605 is squeezed, which drives the arc-shaped striking plate 607 to move synchronously away from the feed hopper 2. At this time, the first spring 608 is squeezed synchronously. Figure 6 As shown, the mutually adaptable structure formed between the cam 603 and the pressure ball 605 is symmetrically arranged at both ends of the arc-shaped striking plate 607, and both linkage shafts 602 are connected to the rotating shaft 502 for transmission. When the rotating shaft 502 rotates, the two linkage shafts 602 can keep their movements synchronized, that is, the two cams 603 can also rotate at the same time and squeeze the adjacent pressure ball 605, so that the thrust on both sides of the arc-shaped striking plate 607 is consistent, so that the movement of the arc-shaped striking plate 607 can be kept on the same axis, thereby improving the stability of the arc-shaped striking plate 607 during movement.

[0066] It should be noted that, for example Figure 4As shown, cam 603 consists of a circular ring structure and a protruding part, while the pressure ball 605 is a spherical object. Both cam 603 and the outer surfaces of the pressure ball 605 are smooth surfaces. When cam 603 rotates, the protruding part on cam 603 gradually rotates closer to the outer surface of the pressure ball 605. When the protruding part of cam 603 contacts the pressure ball 605, because the diameter of the protruding part of cam 603 is larger than the diameter of the circular ring structure, the rotation of cam 603 allows the protruding part to slide across the surface of the pressure ball 605. When the protruding part of cam 603 and the outer surface of the pressure ball 605 slide in contact, due to the reduced space, cam 603 exerts a squeezing effect on the pressure ball 605, pushing the pressure ball 605 away from cam 603. At this time, through the change in the position of the pressure ball 605, the arc-shaped striking plate 60... 7. The position changes synchronously, and the arc-shaped striking plate 607 moves away from the feed hopper 2, so that the arc-shaped striking plate 607 and the outer wall of the feed hopper 2 gradually lose contact. At this time, the first spring 608 is compressed. When the cam 603 continues to rotate, and its protruding part loses contact with the pressure ball 605, the squeezing effect of the protruding part of the cam 603 on the pressure ball 605 disappears. Under the elastic force of the first spring 608, the arc-shaped striking plate 607 can be pushed towards the feed hopper 2, so that the arc-shaped striking plate 607 re-adhere to the outer wall of the feed hopper 2. This process is repeated, so that the arc-shaped striking plate 607 can form a striking effect on the outer wall of the feed hopper 2, and the outer wall of the feed hopper 2 vibrates during the striking process. This vibration can effectively reduce the occurrence of coal dust impurities generated during the feeding of coal raw materials adhering to the inner wall of the feed hopper 2.

[0067] Furthermore, by setting the movement of the arc-shaped patting plate 607 to follow the rotation of the rotating shaft 502 synchronously, the outer wall of the feed hopper 2 can be patted simultaneously while the coal raw material is intermittently and quantitatively fed. This allows the vibration generated during patting to remove coal dust and impurities remaining on the inner wall of the feed hopper 2 during the feeding of the coal raw material. This saves energy consumption and eliminates the need for manual cleaning by workers, making the operation process more complete, the structure more compact, and effectively improving the automation level of the equipment.

[0068] like Figure 2 , Figure 3 as well as Figure 6 As shown, since the arc-shaped striking plates 607 are symmetrically arranged on the outer side of the feed hopper 2, and each arc-shaped striking plate 607 is fixedly mounted with an I-shaped rod 609, which is slidably connected to the fixed frame 4, when the arc-shaped striking plates 607 move through the cooperation of the cam 603 and the pressure ball 605, the I-shaped rod 609 can provide a limiting basis for the movement of the arc-shaped striking plates 607, so that the I-shaped rod 609 slides synchronously through the fixed frame 4, so that the arc-shaped striking plates 607 can move on the same axis. Figure 3and Figure 6 As shown, two I-shaped rods 609 are fixedly connected to sliding columns 610 at their opposing ends. U-shaped frames 613 are symmetrically fixed on the inner walls of both sides of the fixed frame 4. A linkage frame 611 is rotatably connected to the U-shaped frame 613, and straight slots 612 are symmetrically opened on both sides of the linkage frame 611. The sliding column 610 is slidably connected through and traverses the straight slots 612. When the arc-shaped striking plate 607 moves away from the feed hopper 2 and synchronously drives the I-shaped rods 609 to move (it should be noted that since only one of the two arc-shaped striking plates 607 is set up, it moves through the cooperation of the cam 603 and the pressure ball 605. Therefore, in the initial stage of use, only one arc-shaped striking plate 607 is driven to move, while the I-shaped rod 609 connected to the arc-shaped striking plate 607 will synchronously follow and move away from the other I-shaped rod 609), it can drive the sliding column set at the end of the I-shaped rod 609. The sliding column 610 slides within the straight groove 612, and through the sliding of the sliding column 610, the linkage frame 611 can be driven to rotate on the U-shaped frame 613. At this time, the other end of the linkage frame 611 passes through the sliding column 610 slidably connected through the straight groove 612. Under the rotation of the linkage frame 611, it can be pushed synchronously to slide within the straight groove 612, and push another I-shaped rod 609, so that the two I-shaped rods 609 move in opposite directions. Since the I-shaped rod 609 is installed on the arc-shaped striking plate 607, when the two I-shaped rods 609 move in opposite directions, the two arc-shaped striking plates 607 also move synchronously away from the feed hopper 2, so that the two arc-shaped striking plates 607 can move synchronously and strike the outer wall of the feed hopper 2 synchronously. This design can effectively reduce the number of transmission components 601, cam 603 and pressure ball 605 related structures, and realize the synchronous movement between the two arc-shaped striking plates 607.

[0070] The following describes the working process of the water mist spraying mechanism 7 simultaneously spraying water mist into the interior of the machine body 1 while the coal raw material is intermittently fed:

[0071] When the linkage shaft 602 rotates, it drives the cam 603 to rotate synchronously, such as Figure 2 , Figure 5 , Figure 6 as well as Figure 9As shown, sector gears 701 are fixedly connected to both opposite ends of the linkage shaft 602, and toothed plates 709 are meshed on the sides of the sector gears 701. The toothed plates 709 are fixedly mounted on the vertical rod 708. As the linkage shaft 602 rotates, the sector gears 701 also rotate synchronously around the linkage shaft 602. Initially, the sector gears 701 do not mesh with the toothed plates 709. As the sector gears 701 rotate, their teeth gradually approach the toothed plates 709 and eventually mesh with them. Through the meshing of the teeth, the toothed plates 709 can be driven to move upwards synchronously with the vertical rod 708. Figure 7 , Figure 8 as well as Figure 9As shown, an annular top plate 710 is fixedly installed at the top of the vertical rod 708, and the annular top plate 710 is slidably mounted on the outer wall of the feed hopper 2. When the vertical rod 708 moves upward, it can simultaneously drive the annular top plate 710 to slide upward on the outer wall of the feed hopper 2, thereby driving multiple vertical rods 708 to move upward synchronously. Since a piston rod 706 is fixedly connected to the bottom of the vertical rod 708, and the piston rod 706 is slidably and sealed inside the T-shaped water supply pipe 704, and a second spring 707 is fixedly connected between the vertical rod 708 and the T-shaped water supply pipe 704, when the vertical rod 708 moves upward, it can drive the piston rod 706 to slide upward synchronously inside the T-shaped water supply pipe 704. At the same time, the second spring 707 is subjected to the force of the vertical rod 708. The upward force will also be stretched. Since the lower end of the fixed frame 4 is fixedly connected to the water storage ring 702, and the water storage ring 702 can be connected to an external container containing water through the water guide pipe 703, and the T-shaped water supply pipe 704 is fixedly connected to the water storage ring 702, and a one-way valve is set between the T-shaped water supply pipe 704 and the water storage ring 702, when the vertical rod 708 moves and drives the piston rod 706 to slide upward synchronously inside the T-shaped water supply pipe 704, water can be drawn from the inside of the water storage ring 702 into the inside of the T-shaped water supply pipe 704 through the one-way valve. Since the feeding movement of the coal raw material continues, the linkage shaft 602 will also continue to rotate, so that the sector gear 701 continues to rotate. As wheel 701 continues to rotate, it gradually loses contact with toothed plate 709, disengaging from its meshing. With the meshing effect on toothed plate 709 gone, the elastic force of the second spring 707 pulls vertical rod 708 downwards, restoring it to its initial position. This downward movement of vertical rod 708 also drives piston rod 706 to slide downwards within the T-shaped water pipe 704, atomizing the pumped water and spraying it out as a mist through the atomizing nozzle 705 installed at the end of the T-shaped water pipe 704 away from the water storage ring 702. Since the T-shaped water pipe 704 is fixedly connected to the lower end of the feed hopper 2, and the atomizing nozzle 705 is simultaneously installed within the feed hopper 2, the water is atomized and sprayed out as a mist. The water mist sprayed by the atomizing nozzle 705 directly acts on the surface of the coal raw material being fed, spraying water mist onto the coal raw material during the feeding process. This prevents the coal raw material from becoming too dry in a dry environment, which could lead to crushing and breakage during feeding. During this process, because the T-shaped water supply pipe 704 is arranged in a ring at equal intervals on the water storage ring 702, multiple atomizing nozzles 705 are evenly distributed in different positions within the feed hopper 2. During use, the coal raw material can be sprayed from different directions, thereby increasing the uniformity of water mist reception on the coal and further improving the effect of spraying water mist onto the coal raw material, so as to increase the moisture content of the coal raw material and prevent it from becoming too dry.
